Why tumblr?

I opened that tumblr to mirror my social media posts about the MINIDISKO project. The advantage of tumblr: unlike instagram, Facebook or Google+ you can subscribe to my tumblr feed and add it to your RSS reader. Another reason: tumblr is more open! It's easy to share and to access content, while other social media websites behave more like closed "apps", making it very difficult or impossible to share content across different platforms.
